Change Interval for Your Infiniti FX35 Transmission Fluid

Maintaining the right change interval for your transmission fluid is essential for the longevity and performance of your 2008 Infiniti FX35. While the manufacturer may provide a general recommendation, real-world experiences and expert opinions can help you determine the best approach for your specific driving conditions.

Recommended Change Interval

For the 2008 Infiniti FX35, the general recommendation for changing the transmission fluid is typically around:

• 30,000 to 60,000 miles (approximately 48,000 to 96,000 km) for normal driving conditions.
• 15,000 to 30,000 miles (approximately 24,000 to 48,000 km) for severe driving conditions, such as frequent towing, stop-and-go traffic, or extreme temperatures.

These intervals can vary based on individual driving habits and conditions. Always consult your owner’s manual for the most accurate information.

Partial Transmission Oil Changes

One important aspect to consider is that in many cases, a complete transmission fluid change is not feasible without removing the transmission from the vehicle. This is primarily due to the design of modern automatic transmissions, which often do not have a drain plug for easy fluid removal. Instead, fluid changes are typically performed through a process known as a partial oil change.

What is a Partial Oil Change?

A partial oil change involves removing a portion of the old transmission fluid and replacing it with new fluid. This method is often more practical and less labor-intensive than a full fluid change. Here are some key points regarding partial oil changes:

• Fluid Replacement: Typically, only about 30-50% of the total fluid is replaced during a partial change, which helps to refresh the fluid without the need for extensive disassembly.
• Frequency: Many owners opt for partial changes more frequently, especially if they drive under severe conditions, to maintain optimal fluid quality.
• Cost-Effective: Partial changes are generally less expensive than full changes, making them a more accessible option for regular maintenance.

Justification for Partial Changes

The rationale behind partial oil changes is supported by various automotive experts and statistical data. According to the Automatic Transmission Rebuilders Association (ATRA), regular fluid maintenance is crucial for transmission health. They emphasize that even partial fluid changes can significantly improve the fluid’s performance and extend the life of the transmission.

Additionally, a study published by the Society of Automotive Engineers (SAE) indicates that maintaining clean transmission fluid can reduce wear on internal components, leading to fewer repairs and a longer lifespan for the transmission. Regularly replacing a portion of the fluid helps to remove contaminants and maintain the fluid’s effectiveness.

In summary, while the recommended change interval for your Infiniti FX35 is essential, understanding the practicality of partial transmission oil changes can help you maintain your vehicle’s performance without the need for extensive service. Regular maintenance, whether through partial changes or adhering to the recommended intervals, is key to keeping your transmission in top shape.
